hi!well,your question is very difficult to tell the truth...i will try to list the advantages /disadvantages of cyprus compared to australia and other places
advantages =1)very safe compared to other countries,2)very satisfactory living standards compared to many other european countries,3)very good education level,4)many countries are very close so its a very good starting point for travelling and vacations,most european destinations are within 4-4,5 hours by plane,there are ships connecting cyprus to israel,egypt,lebanon,greece,syria,5)beautiful weather and friendly people
disadvantages =1)small island and small society (~750,000 inhabitants),2)bad public transportation bc everyone has his/her own car,3)you will not have the job opportunities you have in other bigger countries(of course this depends on what your profession is).
another thing you should know is that you can get along without knowing greek very well bc most people speak english. there are many english language schools,but they are all of them private and you have to pay tuition fee. in public schools the language of teaching is greek and they are free. your children at their age if they register in a public school will not have a language problem,it will take them about 6-7months to learn the language only(my best friend is a primary school teacher and he has taught many foreign speaking children in public schools and he told me that 6-7 months is the max time for a child to pick up the language,usually they do it within 4-5 months).
